1 Claim.

This invention is directed to an improvement in brushes and is designedparticularly to provide a variety of brushes and attachments therefor toinsure more eiective use and result from the brush employed.

The primary object of the present invention is to provide a series ofbrushes, one of which is designed more particularly for hand operation,and capable of use in connection with the brush fluid, such as water orair, for use on the surface to which the brush is being applied, thebrush being particularly designed to permit its use in connection withacids, perfumes, or the like, whereby the brush may be better adaptedfor special uses.

A further object of the invention is the provision of a ferrule designedmore particularly in connection with a fountain brush, which ferruleprovides a means for gripping the brush for use in a convenient andsecure manner, and further provides for the introduction of a cleansingfluid at will for distribution through the fountain brush.

A further object of the invention is the provision of means by which theferrule of the fountain brush may be flexibly connected to a fixture toprevent the falling of the brush in its use in external cleansing.

A further object of the invention is the provision of a removable bumperdesigned to be slidably connected with the brush body and frictionallyhel-d, without other fastening means, in position to safeguard anysurface or article with which the brush may accidentally contact.

The invention is illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a fountain brush showing the means forsupplying fluid thereto and the flexible means for connecting the brushagainst complete release.

Figure 2 is a section on line 2-2 of Figure l.

Figure 3 is a transverse sectional View through the brush and ferrule.

Figure 4 is a perspective view of one section of the flexible bumper foruse in connection with the brush.

In the drawing, l have illustrated the improv-ement applied to aconventional iiat brush 4|. The improvement in this particular residesin the ferrule to be connected to the brush for use in handling thebrush, connecting it against complete loss or separation, anddistributing a cleansing fluid to the bristles 42 of the brush. Thebrush body is hollow, providing a chamber 43, through the bottom wall ofwhich openings 44 lead to the bristles. The upper wall 45 of the chamberis preferably convex on its upper surface and centrally recessedthroughout its full width to receive a flat plate 46 of the nipple 41.

This nipple 41 is provided with an outstanding extension 48 which isinteriorly threaded at 49 and which communicates through an opening 50in the upper wall 45 of the brush head with the chamber 43. Theextension 48 is arranged at an inclination to the upper surface of thebrush head and is positioned on one side edge of the brush, theinclination and vpositioning of the extension being such that when thebrush head is grasped in the hand forA use, the nipple may be receivedbetween the thumb and first nger of the grasping hand to insure a moreeffective tension or grip of the brush head. y

The nipple 41 is secured in the recess in the upper wall 45 of the brushhead through the medium of a bolt 5| which passes entirely through thebrush head and is secured by a nut to facilitate -convenient removal.The nipple is further provided with a laterally projecting lip 52 formedwith an opening 53 to provide for the removable connection of a strap,chain or the like 54 by which the brush, through the medium of thenipple, may be secured to any fixture, for exam-ple the safety belt ofthe user in the outside washing of the windows of buildings, in order toprevent falling of the brush an-d consequent danger to pedestrians onthe pavement below.

The flat brush head is provided with end and side buffer means, shownmore particularly in Figure 4, and including duplicate end elementscomprising a flat plate-like section 66 and a marginal rim extendingabove and below the plate indicated at El. The buffer elements are ofrubber or like material rand the brush head is slotted longitudinally ofthe upper wall 45. This slot 68 is arranged to receive the plate-like`sec-y tion 6B of the buffer element which is moved longitudinally ofthe slot, so that the rim Bl overlies vthe end wall of the brush headand a material portion of the side walls.

Of course, the buffer elements are arranged at both ends of the brushhead and such elements are preferably secured by a screw pass-V of thebrush. This constitutes a removable buierA which will prevent injuriouseffect through 'any 2 y 2,267,256 Contact of the brush body with anobject during to receive a flexible connector, a nipple carried the useof the brush.
